@therevoman hi Nate would you mind adding coral tpu pcie support for your project?

my lspci output looks like this:

I use the node feature discovery to find nodes with usb and pci devices like this:

          - name: "coral-tpu-usb"
            matchOn:
              - usbId:
                  vendor: ["1a6e", "18d1"]
          - name: "coral-tpu-pci"
            matchOn:
              - pciId:
                  vendor: ["0880", "1ac1"]
